深交所发布港股通标的证券名单调整公告。

US mortgage rates rose to 6.49%, reversing last week's decline, as renewed US-Iran escalation raised concerns that oil prices and borrowing costs could climb. Freddie Mac said on Thursday its 30-year fixed-rate mortgage average rose to 6.43% from a week earlier; it was 6.72% a year ago. The conflict since late February has weighed on the housing market, and hopes that a prior ceasefire would ease geopolitical risk and stabilise borrowing costs have dimmed after this week's escalation. High mortgage rates are hindering buyers and may prevent sales improvement in 2026, and the current Iran situation could keep rates elevated, Realtor.com senior economist Joel Berna said.
